bison 3.4.1 writes the header file before the c++ file. Our makefile
rules make the header files depend on the c++ files, so we need to
fix the timestamps accordingly.
Note we only want these enabled when building the compiler and runtime
binaries. If we included the ICARUS_VPI_CONST definition in the global
CPP_FLAGS, that would propagate to the flags used by iverilog-vpi, so
would affect compilation of user VPI code.
When for example assigning to foo[<x>] within a contitional, and
doing synthesis, we need to create a NetSubstitute device to manage
the l-value bit selects.
Before this patch, WARNING_FLAGS applied to both C and C++,
and WARNING_FLAGS_CXX applied to C++ only.
This patch adds a WARNING_FLAGS_CC that applies to C only.
That change should be generally useful; in particular the C
code is almost ready for -Wstrict-prototypes, which does not
apply to C++.
-Wextra (or -W) used to only apply to C++ via WARNING_FLAGS_CXX.
This patch moves it to WARNING_FLAGS, to apply to both C and C++.
Unfortunately, that triggers a ton of warnings.
For now, cover most of the new warnings up by adding
-Wno-unused -Wno-sign-compare -Wno-type-limits
to WARNING_FLAGS_CC. In the long run, I want to change the C coding
style, and take off these disable-warning flags. But those changes
can dribble in as separate commits; this patch is big enough already.
Actually fix a couple missing-field-initializers in libveriuser/veriusertfs.c.
This provides the ivl_target.h interface for class definitions
and expressions, the vvp code generator support for class objects
and properties, and the vvp run time support. Trivial class objects
now seem to work.
Create stub class objects at the vvp level and generate the code
to invoke that stub. Implement the routines needed to implement
a test for null object references.
Implement through the ivl core to the ivl_target.h API.
Also draft implementation of creating and storing arrays
in the vvp runtime and code generator.
In vvp, create the .var/str variable for representing strings, and
handle strings in the $display system task.
Add to vvp threads the concept of a stack of strings. This is going to
be how complex objects are to me handled in the future: forth-like
operation stacks. Also add the first two instructions to minimally get
strings to work.
In the parser, handle the variable declaration and make it available
to the ivl_target.h code generator. The vvp code generator can use this
information to generate the code for new vvp support.
Not all the lex/yacc (flex/bison) targets were using a consistent syntax.
This patch fixes that and explicitly serializes the *.c/*.cc and *.h build.
Not doing this was causing problem when using make -j. The issue appears to
be that if two targets are specified for a rule (e.g. file.cc file.h: file.y)
make does not realize they are both built by the same call so the rule is
executed twice. Once for the .cc target and once for the .h target. This is
not a problem for a serial build. To work around this only use the .c/.cc
file in the main target and then make the .h file depend on the .c/.cc file
as a sub-target.
Update the line number for a couple cppcheck suppressions and add one for
the pool variable in the vvp directory.
Also move a check for null to the correct place.
This patch adds support for tracing procedural statement execution in vvp.
This is accomplished by adding a new opcode that is inserted before the
code that represents a procedural statement. These opcodes also trigger
a message whenever time advances. By default these opcodes are not added.
To add them, pass the -pfileline=1 flag to the compiler. In the future we
may add support for turning the debug output on and off once the opcodes
have been added with a system task or from the interactive prompt.
Create the v2009.vpi module to include SystemVerilog core
functions, and start out with some of the enum methods.
Add to vvp support for creating enum types, including some
vpi access methods.
This patch adds -Wextra to the compilation flags for C++ files in
the vvp and vpi subdirectories. It also fixes all the problems
found while adding -Wextra. This mostly entailed removing some of
the unused arguments, removing the name for others and using the
correct number of initializers.
This patch adds support for running cppcheck from the Makefile. It also
standardizes the order of some of the targets. It renames vpip_format.c
to vpip_format.cc and fixes the size of the array tables to make room
for the trailing NULL. Found when using a C++ compiler.
This patch updates all the Makefile.in files and configure.in
as follows:
Do not use the -Wall warning flag when using the SunPro compiler.
The SunPro compiler uses -xMD instead of -MD.
There are still more fixes needed before Icarus will compile
on OpenSolaris.
dlltool which is used by both MinGW and Cygwin to create dynamic
libraries must have the name of the executable it creates the
library/information from exactly match the installed executable
name. If we have a suffix then it must be used. This patch adds
that to the build process for vvp since it can be installed with
a suffix. It also modifies the check routines since you must run
vvp with a suffix if the library it links to was built for a
suffixed executable.
We do have one C program in the vvp directory so add CFLAGS to
the Makefile. This patch also modifies the two local programs
tables and version to use -Wall.
These explicit dependencies are not normally needed (because they
are covered by automatic dependency generation) but when the "-jN"
flag is passed to gmake, they help gmake schedule parallel builds.
(cherry picked from commit 5479aaf721)
Try to put all the version stamps into common version_base.h
and version_stamp.h header files. All the source programs then
get their version from these header files.
Also handle the version stamps in the man pages by using the
version_*.h header file contents to edit the version strings
in the man page title bar markers.
This patch removes bin32 from the clean targets since it is no
longer user/created. It adds autom4te.cache to the distclean
target in the main directory. It removes the files in driver
that are not created (lexor.c parse.c, etc.). The *.cc.output
files are no longer created so removing them is not needed.
- Add missing dependency of configure on aclocal.m4.
- Remove config stamp files in make distclean (and fix another for
loop in base make distclean that I missed)
- Add stamp files to .gitignore
Use the time stamp file technique recommended by the autoconf manual
to prevent unneccesary rebuilds because of an unchanged config.h.
Uses the automake trick of generating the stamp files in the
_AC_AM_CONFIG_HEADER_HOOK macro instead of littering the source
directory with stamp-h.in files.
Add an extra ./config.status run after ./config.status --recheck
because with --recheck it doesn't actually try to remake the generated
files (and thus doesn't make the timestamp files). Thus without the
extra run, each stamp-*-h target would need to independently run
./config.status to make sure it wasn't changed by the configuration
change.
An orthogonal fix of how config.status is called in subdirectories.
When in a subdirectory and config.status is called with
../config.status and $(srcdir) is a relative path, config.status gets
confused. Fixed by replacing '../config.status --file=Makefile.in'
with 'cd ..; ./config.status --file=<dir>/Makefile.in'
the vvp_net.h header file is getting pretty huge. This divides
the obviously separable signal functor code out into its own
header and source files.
Also, fill out the use of the filter member of the vvp_net_t
object. Test the output of the vvp_net_t against the filter.
The newer mkinstalldirs can handle paths that have spaces in them.
While I'm at it, I also updated the Makefiles so that installation
can also work to DESTDIR directories that have spaces.
Rather then spread VERSION= defines throughout all the makefiles, put
the base version in version_base.in. Use that to generate a version.h
that includes the base version as well as the detailed version.
This reverts commit 31d67fcd3e.
The concensus has been that this causes too many build problems in
the general case and what is needed instead is a way to turn on the
extra warnings for developers only.
The code base is almost shadow-free now, so this won't add much noise to the compiles.
Problems I know about:
lxt{,2}_write.c: patch sent upstream
cflexor.c: exposes gray area of name space boundary
This patch cleans up the Makefile.in files.
We only need to delete config.log in the lower directories.
We reference the *.in files at $(srcdir)/
We need to make distclean for the tgt-(fpga,pal,verilog) directories.
This is to cleanup the Makefile.
Add some missing "rm -r f dep"
Collapse all the configure checks to a single configure script in
the root of the source tree. This makes the configure process run
a lot faster, expecially on Windows systems that are slower in general.
Tran islands are a kinds of island, so seperate the tran handling
from the core island concept. This will allow for creating new
kinds of islands. (Think analog.)
This patch removes the CVS ident information from the Makefile.in
files it also puts in the current version 0.9.devel for the default
VERSION definition. This is normally passed down, but a local make
will use the value from the local Makefile. This will eventually be
replaced with a file based version to give us just one place to
reliably modify the version.
